I am definitely not C+V with the indoor trainer. I use a Wahoo Kickr Snap. Smart trainer has made it so I actually get a quality workout in rather than drag myself unwillingly to the old existence unit and suffer for 45 minutes until I get bored and quit. I leave my old aluminum TT bike on the trainer.
If you’re going to ride a steel bike indoors, use a shield over the top tube or rinse and wipe down carefully after each ride. Sweat collects under the top tube and has rusted out many a nice frame.
